I want to dominate everyone again >.<

Sry for bad English! //Samme:P

90% of hacks aren't working, that's why your game crashing. And check out pbbans.com for your GUID. Maybe you already in banlist?

Have checked and i was banned but the thing is that the hack is working on my friends computer without crashing, and his pc is nearly the same as mine(same ram and video card and so on...)
Could it be that the system repair or something deleted a important file to the hack? :S + its crashing when im playing on not pb servers.
But thank u for answer

I dont think its patched cuz my friend can use it so :3
But thanks

You checked and you were banned? Surely that answers your question?

Also I noticed Xfire has started causing my game to crash again so try closing xfire if you have it running and you're not banned.
